There were many reasons that the people in Europe wanted to explore. One of them was that Europe was dirty all over the place. Another was the fact that Monarchs wanted more land to their name, so they sent explorers to find more land.
Go somewhere else then!
This place is too dirty!
Yet another reason was that they wanted to know what was beyond the vast ocean.
What do you think is out there?
I don't know... But I want to.
So people set out on voyages some trying to find new land, and others trying to find safer and faster routes to Asia.
